I just ordered all the parts for the carburator, tune up, oil, valve adjustments for my generator identical to yours. Thank you so much for this tutorial. You did a fantastic job. I'm impressed.
this is a GREAT video, but for anyone reading this that does their oil changes you should know that the type of oil used is temperature sensitive. Refer to your owners manual for which grade of oil to use - 15w-40 is the appropriate grade for the summer. If you're in a colder environment where it freezes during the winter you'll need a lighter oil for the winter. I travel a LOT in my RV so I carry all 3 grades of oil with me so no matter what I have the appropriate oil on hand.
Great Toutorial young man! Your a natural and ur attention to detail is impeccable!! Bravo, I really needed this to learn about my newly aquired Onan 5500 Marquis/2000 Tiffin Allegro Motorhome. Thank You!
Great video and instructions. I have a few questions - what is the name of the off road oil. I live in Florida and my generator gets extremely hot. - do you have / or can you make a video on the breaker panel wires change. The wire to the breaker panel is losing contact and causing it not to work.
I’m late to the party, but also use T4 15 W-40 in mine. It has about 2000 hours on it. Never a lubrication problem. The Wix number is 57398 . Those are easier to get, but they aren’t as deep. Just get one of those wrenches that fit over the top. On another note, I have 563,000 miles on my 7.3 with that same oil. It’s never been touched. Not even injectors.
I think it's the same as the other side just use a short extension on the socket like I did to get enough clearance. if it's still too hard maybe try removing the valve cover but I doubt that's necessary. also don't forget to hit like and sub!
I have a 5500 running very rich on start up and have to start at least 3 times to keep it running.Any carb adjustment ?? Once up and running warm runs fine.
the issue is the choke has a spring mechanism that is activated by temperature. i believe if it gets out of adjustment it can lead to the choke staying on too long after start up. my gen does this. the issue is on the right side of the carb. there is a black round piece i think thats where the spring is. if you go to an onan cummins dealer they might be able to pring the service manual pages for how to adjust that bit
Your problem is most likely the choke pull off actuator. Using an ohm meter you can check bi metal heater element on 2 terminals, should read around 6 ohms.
Great video, I have one that has no carb and its a efi. It seems to be backfiring from the throttle. Could this be a problem? I think the valves have not been serviced. It usually backfires when there is some type of load like a aircon. Im hoping to do the valves this weekend but could this be the issue?
@@immortalengines1605 great! Another question when you do you know the piston is at the top dead center?I notice your rotating the rotor but how do you know it is at the top? Ive done this to single piston ones but not two. So I am a bit confused. I want to service the valves
@@alanrubio6708 As you rotate the engine, watch the valves open and close. Exhaust will be first and then intake, once that has happened, keep turning until it gets hard and then you will be close to TDC for that side. Repeat for other side.
Quick question I have no spark what the air code says apparently is the coil i check and is not spark do you have any idea how I can do it thank you so much men.
@@immortalengines1605 yes, I ready change everything oil filter, fresh oil enough, gas filter, gas pump but is running sometimes after 1hr shut down o sometimes less i really appreciate for take your time for answer this question.
I have this same generator and I’ve always had trouble with it shutting down after 45 minutes. Any recommendations? Have lowered the oil level to 1 1/2 quarts as suggested and still have problems. Have replaced spark plugs fuel pumps etc. etc. I always run regularly with fresh fuel etc. and has been an ongoing issue and no one can seem to find the problem?
The fuel pump can cause this issue. There's a screw near the car carb facing you near the Yellow sticker. Loosen it when the generator shuts off, if no fuel pours out, then it's your pump.
I just watched a video from a guy who realized that his shut off AFTER a large load had been turned off .. like when the a/c compressor would stop. It was the spring adjustment and a nut adjustment on the throttle both.
the air box has a small chart to where it recommends a different weight oil depending on the temperature. I just Followed the advice of the cummins Onan guy at my local store. the most important thing is to change the oil and filter on the proper intervals.
@@joeblow8197 Yes it could be the belt, i've replaced one many years ago. try removing the brushes so that you can see the shaft where they make contact. if when you crank the engine the generator shaft doesn't spin then it's 100% the belt.
@@joeblow8197 Sure if you remove the front panel on the left side of the gen you'll see the 2 circuit breakers so if you you look above them way back you should see the generator and a black loom with 2 wires that are connected to a square black plastic brush assembly on the upper part of the gen. I believe it's held on by one screw if you remove it the brushers should come out and you will have the copper contacts exposed on the shaft of the generator. if when you crank that part doesn't spin then the belt came off or broke.
The most important part is to follow the recommended oil change intervals by the manufacturer. I would call a Cumins/Onan and ask about the synthetic oil. I am not sure about it.
Seems I read in the manual they don’t like it but like the gentleman have posted below, as long as you follow the same interval, it should be fine. The 5/40 T6 probably does better in cooler temperatures, Especially during warm-up. I’ve got a couple thousand hours on the T4 so it doesn’t owe me anything. Sometimes it runs a week straight if we are out with the toy haulers.
